I bought one roll of reflectix, one roll of aluminum foil tape, and one roll of velcro and this is what turned out.




I was able to make 25 cozys that will house a quart size bag. The materials cost 25 dollars so it cost me 1 dollar each to make instead of 12 dollars from antigravitygear.
All I did was cut, fold, and tape.

Nice. Wanna sell one? Email me at jhaura *__at__* gmail *__dot__* com.

Excellent work! Can you post a weight?

weight is 1.1-1.2oz, some weighed in at 1.1 and others at 1.2.

Looks like a nice way to add a little extra insulation for your feet on a cold night, especially if it could open up without causing problems with the tape.

Jhaura: You can find this stuff in the insulation area of any building supply store... and all you have to do is cut it out with some scissors and then fold and tape. Also get some self adhesive velco if you want for sealing the flap.

One thing I noticed about these though is that they are like a pocket... which you load from the top. I like the anti-gravity design of the frezzer bag cozy being like wings that open up and fold over the bag. That's what I use (they threw it in for free with a big order I made). I think the top-loading pocket might be slightly more cumbersome (just slightly) to load.

You know, with a little trial and error,(maybe a lot of error), one could try some imaginative folding techniques to create gussets in the taped bottom and the one taped side. Any origami experts out there with free time?
